Great Dodecahedron

This is the dual of the small stellated dodecahedron, and is one of the four Kepler-Poinsot solids. It consists of twelve intersecting pentagons. It is also a stellation of the dodecahedron.

To give the model internal support, I printed out three big pentagons to fit inside, and built three of the star parts shown on the left.
The three strengthened parts fit together, with other trihedral dimples filling in the gaps to complete the model.
